Overview
Replacement ball socket end cap for LaVanture / SPD style gas springs. This cap fits a 10mm ball and 6mm shaft and is used on many gas shock springs and similar applications.
Price is for one replacement cap. Match your existing end fitting, ball size, and shaft size before ordering.
R&P Service Insight
Gas spring end fittings are size-sensitive parts. Matching the printed strut number is helpful when replacing a full spring, but when replacing only the cap, the most important checks are the ball socket size, shaft size, and physical end fitting style.
- This listing is for the end cap only, not the complete gas spring.
- Confirm 10mm ball size and 6mm shaft size before ordering.
- If replacing the full gas spring, match the product number, force, extended length, compressed length, and stroke.

R&P Knowledge Hub
Gas spring end caps attach the strut rod to a ball stud or mounting bracket. A worn or broken socket can allow the gas spring to pop loose even when the strut itself still has pressure.
When replacing only the end cap, match the socket size and shaft thread. When replacing the full gas spring, match the printed product number whenever possible.
Brand & Fitment Note
This replacement cap is listed for LaVanture / SPD style gas spring applications where the existing fitting, 10mm ball size, and 6mm shaft size match. Compatibility should be verified before ordering.
R&P Repair Insight
If your gas spring still has proper lifting force but the socket is cracked, worn, or popping off the ball stud, replacing the end cap may solve the issue. If the strut no longer holds pressure or does not support the door, hatch, lid, or ramp, the complete gas spring may need to be replaced instead.
Features

Use this chart as a reference only. Always confirm your existing gas spring product number, force, extended length, compressed length, stroke, rod diameter, tube diameter, and end fitting before ordering replacement parts.
Final Verification Note
Before ordering, confirm that your application uses a 10mm ball and 6mm shaft and that your existing end cap matches this replacement style. If replacing the full gas spring, verify the complete strut specifications instead of relying on the end cap number alone.
